Multisite: Show broken themes in network admin (too)

[ocean90]

If we want to inform super admins about a broken theme we should do it right.

At the moment it's only displayed on wp-admin/themes.php, also if the theme isn't activated for the site and where a super admin probably won't take a look.

See [20151] and #20103.

Enable/Disable actions shouldn't be available.

See 20099.patch​

Replying to ocean90:

Enable/Disable actions shouldn't be available.

I thought about that. But let's say a broken theme was enabled before it was broken, and they want to disable it before fixing it. Unless we are to automatically 'disable' themes when you hit the broken themes page, it's easier to just leave the links. It is pretty evident that the theme is omitted because it is broken.

That said, because I kept broken themes excluded from 'all', searching doesn't work. Not sure how exactly to fix that.

Going to prevent enabling but allow disabling and include broken themes in search results.

In [20160]:

Don't show the Network Enable link for broken themes. Include broken themes in searching on network/themes.php. fixes #20099, see #20103.
